statement of the problem: the head and neck region is an uncommon site for metastatic involvement, but it can be the first and only symptom of primary cancer. the incidence of these tumors and their primary origins are limited in iranian patients. purpose: therefore, this retrospective study aimed to investigate the frequency and the common related clinical manifestations, as well as, the most ...

Background and aim: Head and neck cancers are the tenth most common cancers worldwide. Since these cancers can cause severe complications and mortality, early diagnosis and investigation of their prevalence in various regions may be life-saving. Therefore, this study evaluated the prevalence of head and neck cancer over a 10-year period in Gilan province, Iran. Materials and methods: This is a...

Extracranial carotid stenosis is a known complication of external irradiation to the head and neck region. We report on a patient with previous carotid endarterectomy for irradiation-associated carotid stenosis. This patient developed symptomatic carotid stenosis over the ipsilateral common carotid artery proximal to the previous endarterectomy site 3 years later, and was successfully treated w...

BACKGROUND In recurrent head and neck cancer, therapeutic options are limited and high-quality evidence is rare. The purpose of this report was to present our experience of CT-guided interstitial high-dose rate (HDR) brachytherapy in 4 challenging cases of inoperable recurrent head and neck cancer. METHODS A 53-year-old man with mucosal melanoma of the paranasal sinuses, a 61-year-old man wit...

Taste loss in human patients following radiotherapy for head and neck cancer is a common and significant problem, but the cellular mechanisms underlying this loss are not understood. Taste stimuli are transduced by receptor cells within taste buds, and like epidermal cells, taste cells are regularly replaced throughout adult life. This renewal relies on progenitor cells adjacent to taste buds, ...

Management of irradiated patients with cancer in the head and neck region represents a challenge for multidisciplinary teams. Radiotherapy promotes cellular and vascular decrease that results in a low response rate in the healing. Consequently, surgical procedures in irradiated tissues present high rates of complication. Osteoradionecrosis (ORN) is the most severe sequelae caused by radiotherap...

  Background: Office workers spend a long period of time behind a computer during working hours. The relation between the posture of sitting during work with computer and neck pain is still debatable. Even though some researchers claim a significant difference in head posture between patients with neck pain and pain-free participants, the FHP (forward head posture) has not always been associate...

PURPOSE Radiotherapy is commonly used to treat the majority of patients with head and neck cancers. Salivary glands in the radiation field are dramatically affected by this procedure. The purpose of this study was to examine pharmacokinetic characteristics of the stable nitroxide 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl (tempol) with respect to radioprotection of the salivary glands. EX...

The reproducibility of patient setup is an important issue for head and neck cancers treated with intensity-modulated radiation therapy (IMRT). In this study, an image-guided radiation therapy (IGRT) system has been used to minimize the uncertainty of patient setup while standard thermoplastic masks were used to provide adequate immobilization for the head and neck. However, they do not provide...

Introduction: Nasopharyngeal cancer (NPC) is a prevalent diagnosis of head and neck cancers (HNC) in Asia. In Indonesia, it estimated that there are 12,000 new cases per year. Case Presentation: The author reports 25-year-old male patient with recurrent NPC. This was first diagnosed NPC stage IVB 2013 treated by chemoradiation. 2016, he found another mass his neck. biopsy result showed the recu...
